Avoid colliding with the sentinels, hopefully unbreaking

Revert "SimplifyCFG: GEPs with just one non-constant index are also cheap."2011-02-25T10:33:33ZBenjamin Kramerbenny.kra@googlemail.com2011-02-25T10:33:33Zurn:sha1:278be783b5068e6f87f16bc9b69a77e0bc958f9f
Yes, there are other types than i8* and GEPs on them can produce an add+multiply.
We don't consider that cheap enough to be speculatively executed.

itself without going via a phi node then we could return false here in
spite of making a change. Also, tweak the comment because this method
can (and always could) return true without deleting the original phi node.
For example, if the phi node was used by a read-only invoke instruction
which is used by another phi node phi2 which is only used by and only uses
the invoke, then phi2 would be deleted but not the invoke instruction and
not the original phi node.

should be that if the phi is used by a side-effect free instruction with
no uses then the phi and the instruction now get zapped (checked by the
unittest).

any instructions to DCE, so delete the test.
Also renamed J and JP to I and IP in RecursivelyDeleteDeadPHINode.
